Welding exposures increases FEV1 loss in smokers

Welding exposures increases FEV1 loss in smokers
A meta-analysis of longitudinal studies shows increased FEV1 decline in welders, the feffect seen mostly in smokers, where the mean FEV1  loss was 13.7ml/year. The effect in non-smokers was statistically non-significant at -3.8ml/year
